HMR1 series · spec 020 · Helical, flange-mount family
HMR1-020 helical rotary actuator
200 Nm driving torque at 210 bar, 90° / 180° / 270° / 360° rotation, in flange mount. The HMR1-020 is 1st of 15 sizes in the HMR1 flange-mount range, built to order for general positioning, swing and clamping duties where the actuator face-bolts to a machined flange on the machine, and the same housing is specified across four standard rotations.
It is the smallest size in the HMR1 range, below HMR1-035 at 340 Nm.

HMR1 is rated at 210 bar continuous; the flange pilot diameter and bolt circle are what decide whether the unit sits square on your existing bracket. HMR1 covers 90°, 180°, 270° and 360° as standard rotations; the flange mount is implicit in the order code.
What the code means
Every HMR1 unit is specified the same way. If your tag carries a different suffix, the base size is still HMR1-020.

Cross reference
Models customers compare with HMR1-020
These are the models that sit in the same torque class and come up in the same enquiries. They are comparable references, not validated substitutions — we confirm the mounting pattern, shaft and port details against your unit before quoting.
| Make | Model | Reference page |
|---|---|---|

Comparable performance based on rated torque class for engineering comparison. The mounting interface must be confirmed by our engineering team before quotation.
What we check before quoting
On the unit
- Mounting pattern and bolt spacing
- Shaft type, spline or keyway, and length
- Port size, thread form and valve arrangement
On the machine
- Available envelope and tie-rod clearance
- Working pressure and flow at the actuator
- Rotation stops and any mechanical limits
HMR1-020 questions
What can I use in place of an HMR1-020?
We build the HMR1-020 itself to order, and where an HMR1-020 is no longer available we quote the closest HM HMR1 build and confirm the fit against your unit. We do not publish a one-to-one substitution table, because mounting pattern, shaft, port thread and valve arrangement have to match your machine, not just the torque class.
Is HMR1-020 a direct replacement for HKS DA-H 40?
No — we do not claim a verified drop-in for any other make. Enquiries for this torque class arrive tagged as HKS DA-H 40, HKS I-DA-H 40; we treat those as comparable references and compare rated torque, mounting interface, shaft and ports before quoting the HMR1-020 build that suits your machine.
How is the HMR1-020 order code put together?
The pattern is HMR1-{spec}-{angle}-{output}-{valve}. A worked example is HMR1-020-180-KS-CS. Rotation, mount, output and valve are chosen per machine, so the code on your drawing is what we build to.
